. To-aZl whom e't may concern:

Beit known that l, Eowrn A. OLLEY, a --citizen of the United States,residing at Syracuse, in %;he county of Gnondsga and. State of New York,have invented a certain new and useful Panel-Board Construction, ofwhich the followinc is a specification.

This invention has for its object a panel board construction, and.particularly the production of an elecirical appliance by which the loadcircuit controlling devices as the switches and the fuse connections areso arrangedthat the widthwise rl -ension oi the panel board ismaterially reduced; and the invention consists in the combinations andconstructions hereinafter set forth and vclaimed.

In describing this im'en zior, reference is had to the accompanyingdrawings, in which like characters designate corresponding parts in allthe views.

Figure l is a plan view of a panel hoard embodying my invention.

Fig. 2 is an eniargcd section on the plane of line A--A, Fig. l.

Fig. 3 is an elevation, partly in. section, looking to the right in 2.parts being omitted.

Fig. A} is a plan view of the inner base of the appliance, the switchmechanism being removed.

My electrical appliance for panel boards comprises. generally.supporring means and circuit controlling devices carried by thesupporting means and connected in scrics, said dc-viccs being nrcicrablyarranged one above the other. l no supporting means in this form of myinvention comprises two insulating bases as inner and outer units. oneextending abovc and incloshg the olncr, and switch and fuse dcviccsinounrcd respectively on the units.

hlore specifically this appliance compriscs, a base. a switch mounted onthe base and including" terminals, a switch arm movable info and out ofposition to close and open t-hc circuit across tho terminals. andoperating moi-ans for the switch arm, and a second basi rising above ihefirs't'base and supporting an clw-lrical receptacle, as a fusereceptacle. having terminals connected in series with the "formertcrminals, the operating nieansfor the switch arm being oxposcd throughthe sc ond base. and the second base preferably having a shirt inclosingor housing the switch mechanism and also the first base.

1 is the panel or base of the panclboard. 2, 3 are the bus bars, and 4,5. arc the load circuit. bar sections connected, respectively. "to i'chebus bars 2, 3. (5.. 7 are respectively. load circuit. bar sectionspaired with the sections 4, and having their inner ends ofisel'. fromthe panel 1. as at S. and opposed to the inner ends of the sections 4.5. which are oii'set at 8.

9 dcsigniatcs one of the bases of the elcctrical appliance which ismounted on till. panel 1 over the bar sections 4. 7 and has barriers 10,ll separating said sections and resting on the upper face of the pancll.

12, 13 are pairs of terminals of the switch. the terminal 12 of cachpair being connected to the oli'set end S of the corrcsponding barsection of the load circuit bar scciions. as the bar section (3 or 'i'by screws 12. Each terminal 12 is here shown as consisting of a base 1isecured by a screw 15 to the base 9, and an upwardly exiending fiange 16having projectinpfrom one edge thereof. a switch Contact 11. The screws15 extend into the base 9 from the underside thercm: and the screws 1'2scrve r0 electrically councctthe terminals 152 and the bars 5, 7.

Each terminal 13 consists of an upright 18 having a foot 19 at its lowerend sccul'cd to the base 9 by a screw 20 exicnding' into ihe be so andthe foot. from the lower rear side of the base. ihe upright having: alaterally 0xi'cuding switch contact 21 between its ends and a laterallyextending arm :22 at its upper end which rcrminatcs in an arc-shapedportion 223 locafcd ovcr the spucc 'bcrween the switch contacts. in willhe understood that thcrc are two of cach of the terminals 12 and l3.

25 are switch arms which move about an axis. the opposite ends of thoarms 23 moving to and out of cngagcnicn'twith each pair off contacts 17and 21. As there are iwo pairs oi contacts 17. 21. there are two switcharm's The switch heroshown is of the push button type, and as themechanism of this type of switches is well known, further dcscription isthought to be unnecwsary.

The operating means or push buttons of the switch mechanism aredesignated 27, 28 and ext-end upwardly openings in. the top of thesecond base -.o he described.

29 designates the second base which includes a top superposed above theswitch mechanism, and skirt or housing 30 inclosing the switchmechanism, and also inclosing the base 9 and resting at its lower edgeon the panel 1, the skirt having cutouts 37 in its lower edge throughwhich the load circuit bar sections 4, 5, 6, 7 pass. The ush buttons2'4, 28 extend through the top oi the base 29. v

The electrical receptacles mounted on-thc top of the base 29 are hereshown as adapted to receive fuse plugs and each includes a sleeveterminal 31. located in a suitable socket 32 formed integral with the'base 29 and a central terminal 33. Each sleeve terminal includes asuitable base flange 34 which. is overlaid by a washer 35, and thewasher is clamped to hold the sleeve in position by means of pairoldie-metrically disposed screws 36 extendin through the top of the base29 and three ing into the arc-shaped end portion 23 of one of theterminals 13, hence making electrical and mechanical connectiontherewith. Each central terminal 33 consists of a, long screw extendingthrough the body 29 of" the base through the space inclosed by the skirt30, through the base 9 and threading into the ofiset end 8 of the barsection l or 5. Thus the terminals 31, 33 are connected in series withthe switch contacts 17 and 21. The screvvs33," 36, in addition to makingelectrical connection, mechanically secure the base 29 in position.

In operation, assuming that the switch is closed and that fuse plugs areinserted in the fuse plug receptacles to connect the terminals 3'1, 33,the current pames from one bus bar, as 3, through load circuit barsectlon 5, terminal or screw 33 of one fuse plug receptacle, through thefuse plug to sleeve terminal 31, through the screws 36 to one terminal13, and switch contact 21 thereof, thence through. one switch arm 25 toone terminal 12 and thence through one screw 12*, load circuit barsection 7, around through the load circuit, to the bar section 6,vthrough the other screw 12*, terminal 12 electrically connected to thebar section 6,

the companion switch arm 25, switch con tact 21 and terminal 13 on whichsaid contact is provided, through the screws 36, sleeve terminal 31 ofthe other fuse plug receptacle, through the fuse lug in said receptacle,and thence to the ot er load circuit bar section 4 and bar 2 by way ofthe ter- -minal 33 of the last mentioned mosses fuse plug receptacle.

This electrical appliance is particularly advantageous in that the,iuses and switches are so combined that they occupy substantially thesame space ina widthwise direction of the panel board, so that thewidthwise dimension of the panel can be reduced compared with switchboards heretofore in use in which the switches and the fuse receptaclcshave been separate units.

What I claim is 1. An electrical appliance for panel boards,

comprising supporting means, switch and fusercceiving devices carried bythe supporting means, the supporting means comprising a base mountableupon a panel board, the switch device being located within the base andthe fuseerecciving device be-, ing mounted on the top of said baseabovethe switch and switch operating means extending through the top onthe base adjacent the fuse-receiving device whereby .the switch andfuse-receiving devices. occupy. substantially the same area onthe base,substantially as and for the purpose described.

2. 'An electrical appliance for panel boards comprising two 'units, onebeing mounted above the other, one unit comprising a base and switchmechanism mounted thereon, and the other unit comprising a base aiidelectrical receptacles mounted thereon, the operating mechanism for theswitch extending to the outside of the latter unit, and means formechanically and electrically connecting the units togethersubstantially as and for the purpose .descrioed. I

3'. An electrical appliance for panel board comprising inner and outerunits, the inner unit comprising a base and switch mcchanism mountedthereon and having operatlng means extending to the outside of the outerunit and the outer unit comprising a base and fuse-receiving devicescarried on the face thereof, the base having openings through which saidoperating means extend, and means for electrically connecting theterminals of the fuse receiving devices to the switch terminals andmechanicall' connecting the bases together, substantia ly' as and I forthe purpose described. I

In testimony whereof, I have hereunto signed my name at Syracuse, in thecounty of Onondaga, and State of New York, this 30th day of July, 1915.
